10. IC  
IC  
= IQUIESCENT + IINPUTS + IDYNAMIC  
= ICC+ICCDHNT+ICCD(f0/2 + f1N1)  
ICC = Quiescent Current with CMOS input levels  
ICC = Power Supply Current for a TTL HIGH input (VIN=3.4V)  
DH = Duty Cycle for TTL inputs HIGH  
NT = Number of TTL inputs at DH  
ICCD = Dynamic Current caused by an input transition pair  
(HLH or LHL)  
f0  
f1  
= Clock frequency for registered devices, otherwise zero  
= Input signal frequency  
N1 = Number of inputs changing at f1  
All currents are in milliamps and all frequencies are in megahertz.  
11. Values for these conditions are examples of the ICC formula. These limits are specified but not tested.
